Title: Mobile terminal equipment
Inventor: YAMAZAKI HIROO
IPC: H04W64/00
Filed: 1991-06-24
Abstract: PURPOSE:To realize a new mobile terminal, which can maintain the normal operations of a system, by preventing the over load of a base station when a moving object moves at high speed and frequently crosses a position registration zone in a mobile communication system, in which the base station executes an autonomous distribution processing, composed of minimal zones. CONSTITUTION:A mobile terminal 20 receives a base station identification signal notified from the base station and collates the signal with the latest base station identification signal stored in a memory 24. When they are different, it is judged that the terminal crosses the position registration zone, and position registration is executed. Then, the content of the memory 24 is rewritten with any new base station identification number. When the frequency of this reloading is higher than a fixed level, however, it is judged that the terminal is under moving, a power source 28 at the main part of the mobile terminal 20 is turned off, and the operation is interrupted. Therefore, the energy consumption of the mobile terminal can be reduced, any excess position registration traffic is suppressed, and the processing load of the base station can be reduced.
